Fitzroy Minerals contractor starts survey at Caballos

Executive Summary

• Fitzroy Minerals Inc. has commenced a 750-line-kilometre heliborne mobile magnetotelluric (MobileMT) survey at its Caballos copper project in Valparaiso, Chile.
• The survey is designed to cover the entire project area within two days, with interpreted results expected in March 2026.
• The MobileMT technology aims to identify subsurface geologic structures, alteration halos, and lithologies to help trace mineralized breccias and vector towards the origin of mineralized porphyry intrusive centres.

Key Details

• Survey Scope: 750-line-kilometre mobile magnetotelluric (MobileMT) heliborne survey.
• Location: Caballos copper project, Valparaiso, Chile.
• Timeline: Survey to be completed within two days; interpreted results expected in March 2026.
• Technology Purpose: MobileMT aids in identifying subsurface geologic structures, alteration halos, and contrasting lithologies.
• Complementary Data: VLF-EM data will be collected to provide near-surface electromagnetic information, increasing resolution of shallow features.
• Target Depth: The combined methods aim to identify deep-seated faults, lithological contacts, and structures controlling mineral systems from surface to a depth of approximately 1 to 2 kilometres.
• Strategic Objectives:
  • Provide a three-dimensional image of the Caballos project area, including under younger volcanic rocks to the east.
  • Trace the outline of mineralized breccias already intersected through drilling.
  • Vector towards the origin of mineralized breccias containing clasts of mineralized porphyry rocks.
  • Identify areas of electrically conductive sulphides linked to mineralized porphyry intrusive centres and resistive bodies representative of intrusions.

Notable Quotes

• "We expect the MobileMT data will provide a three-dimensional image of the Caballos project area, including under the younger volcanic rocks to the east. We hope the survey will assist us in tracing the outline of the mineralized breccias already intersected through drilling. Further, we hope the survey helps us to vector towards the origin of the mineralized breccias that themselves contain clasts of mineralized porphyry rocks. MobileMT is known for identifying areas of electrically conductive sulphides potentially linked to mineralized porphyry intrusive centres and resistive bodies representative of intrusions." — Merlin Marr-Johnson, President and CEO
